ual question...looking for girls to answer!?

Ok basically here is my issue. When my wife was home we had alot but only when she wanted to. There would be times she would be laying on my bed and she would be just all fine and dandy and I had just gotten out of the shower. At one point in time I walked over to the bed, dropped my towel, got on top of her and started making out with her while moving my hips around and pressing myself against her crotchal region. I did this for like three minutes and then I sat up. She asked me to move because she couldn't see the TV. She wasn't wet or anything. No reaction whatsoever. This happened quite a few times. And usually when we had it was fast and done with in like two minutes. I could never get her wet. I even went down on her a few times and nothing happened. When I asked her why I couldn't get her wet she got all pissy with me. But when she wanted to have she got wet just fine. So heres my question...WHAT THE HELL IS GOING ON??? Do I not turn her on? Is she grossed out by me? HELP!
